Johan Brengesjo decided to develop an alarm clock that wakes you up without sound. Instead, you wear a wireless rubber ring with an integrated vibration device that generates a tactile alarm. To snooze, simply shake your hand. However, there’s a catch — each time you shake your hand to snooze, more movement is required to stop the vibration, so eventually you are awake enough to get up… ingenious really.
